Abstract

In a survey of seed-borne mycofloras of Glycine max, 21 species have been isolated. Alternaria tenuis, Aspergillus spp., Cercospora kikuchii, Penicillium spp. and Fusarium spp. were the predominant fungi. C. kikuchii was isolated more often from purple stained seed than from unstained seed, and Fusarium spp., Phomopsis sp., Aspergillus spp. and Penicillium spp. were isolated less frequently in stained than unstained seeds. In inoculation experiments, C. kikuchii, Colletotrichum dematitum, Phomopsis sp. produced mild to severe symptoms on leaves when suspension of their conidia and mycelia were sprayed on to plants. In soil inoculation experiments, Fusarium oxysporum, F. moniliforme and F. semitectum showed pathogenicity causing seed rot and seedling blight.

1. 충남(忠南) 각지(各地)에서 수집(收集)한 28개(個) 콩종자(種子) sample을 blotter법(法)으로 조사(調査)하였던 바 21종(種)의 균류(菌類)가 검출(檢出)되었고, 특히 부생균(腐生菌)인 Alternaria alternata, Aspergillus spp., Penicillium spp. 등(等)과, 자주빛무늬병균(病菌) (Cercospora kikuchii) 및 Fusarium spp. 이 많이 검출(檢出)되었다. 2. 자주빛무늬가 있는 종자(種子)에서는 무늬가 없는 종자(種子)에 비(比)하여 C. kikuchii가 많이 검출(檢出)되었고 반면(反面)에 Aspergillus spp.나 Penicillium spp.와 같은 부생균(腐生菌)의 오염율(汚染率)과 Phomopsis sp. 및 Fusarium 균(菌)의 이병율(罹病率)이 낮았다. 3. 병원성실험(病原性實驗) 결과(結果) Cercospora kikuchii, Colletotrichum dematium, Fusarium moniliforme, F. oxysporum, F. semitectum, Phomopsls sp.는 병원성(病原性)을 나타내었으나, F. equiseti와 F. solani는 병원성(病原性)이 없었다.
